I have an unusual antique millefiori mushroom paperweight I cannot ID. It has an extremely well made torsade, star cut base, not lead glass (SG 2.480, similar to a number of other unusual antiques). The glass has a distinct blue tinge. The millefiori tuft has been heated a bit much and swirled a little, and the air ring balloons on one side (not uncommon even with the best makers).
Diameter 3 1/4 inch / 84 mm; height 2 inch / 50 mm.
My feeling is 'Bohemian', but I cannot place the canes, and I would welcome other views.
